A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

What is the blockchain? If you don't know, you should; if you do, chances are you still need some clarification on how it actually works. Don Tapscott is here to help, demystifying this world-changing, trust-building technology which, he says, represents nothing less than the second generation of the internet and holds the potential to transform money, business, government and society.

This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges.
Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns.
C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

Transcription:
The internet is evolving into a new technology paradigm based around smart systems, the blockchain, platforms, and IoT
in the coming years, these technologies will interact and converge in new and unpredictable ways
The convergence of IoT and blockchain will be a major part of this evolution, enabling new automated service systems and business models...
but many unresolved issues remain
IOTInternet of Things is the merging of our engineered physical environment with information systems to create smart adaptive objects and environments...
it is a fast-growing, increasingly complex network of connected physical systems that are able to process information and communicate peer to peer in order to enable common services.
These devices are becoming increasingly ubiquitous ranging from autonomous vehicles to sensors monitoring industrial processes, to smart homes and smart cities.
IoT is growing rapidly, according to Gartner the global IoT network will connect 26 billion devices by 2020.
The development of an IOT infrastructure to our economies will probably be the greatest engineering challenge of our time...
dealing with the sheer amount of data due to come on-stream and security are primary concerns...
before mainstream Internet-of-Things adoption can really take hold in a safe and sustainable fashion, these, among other issues, will need to be resolved.
Blockchain
The blockchain is a secure distributed database for recording transactions...
millions of computers networked to create a distributed database for recording and authenticating exchanges of value.
With the blockchain, value of any kind can be exchanged directly peer to peer without a centralized authority to record and validate the transaction.
The blockchain can provide an automated and secure transaction infrastructure for next generation IoT systems...
in its capacity to track billions of connected devices and enable the frictionless processing of transactions and coordination between devices.
This decentralized approach would eliminate single points of failure, bottlenecks and potentially make data and transactions more secure....
creating a more resilient ecosystem for devices to run on.
Likewise, it would automate transactions, enabling fully autonomous service systems; reduce cost and reduce settlement time from days to seconds
One example of an IoT Blockchain system is Slock, a door lock that is connected to a smart contract on the blockchain that controls when and who can open the lock.
“The owner of a Slock can set a deposit amount and a price for renting his property, and the user will pay that deposit through a transaction to the Ethereum blockchain, thereby getting permission to open and close that smart lock through their smart phone.” - Christoph Jentzsch
Such technology bridges the blockchain and the physical world by making automated smart contracts, thus enabling the frictionless and automated temporary exchange of assets such as bikes, parking lots or rooms.
"Smart contracts, a feature of “Bitcoin2.0” technologies such as Ethereum, could soon operate on the Internet of Things (IoT), control objects in the physical world, and power a new decentralized version of the sharing economy, for example sharing services similar to Uber and Airbnb that operate in pure P2P mode without centralized management." - Bitcoin MagazineLeveraging blockchain for IoT offers new ways to automate business processes and build distributed autonomous service systems...
"The true value of the underlying technology -- the blockchain -- has only just begun to be explored, and potential applications to the Internet of Things and Smart Systems are vast."

Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet.
This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

I wanted to demonstrate that the concept of a blockchain that powers almost all of the modern cryptocurrencies is very simple at its core.
Bitcoin, Ethereum, Litecoin etc all are based on this blockchain technology. Many people think that the blockchain is a complicated thing while at it's core its just a clever use case of hashes.

Forget the currency; it’s the protocol behind it that matters. Blockchains will mutate and take over everything we do on the Web.
Trusting strangers with your digital information may sound silly, but it’s actually a revolution in distributed computing. And one day, systems like Bitcoin could be the future of all secure digital transactions. Read more: http://bit.ly/29jiJ3B

Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.

Internet of Things

The Internet of Things (IoT) is the network of physical objects—devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data. The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit; when IoT is augmented with sensors and actuators, the technology becomes an instance of the more general class of cyber-physical systems, which also encompasses technologies such as smart grids, smart homes, intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

Behlendorf, raised in Southern California, became interested in the early development of the Internet while he was a student at the University of California, Berkeley in the early 1990s. One of his first projects was an electronic mailing list and online music resource, SFRaves, which a friend persuaded him to start in 1992.
Behlendorf was an early participant and the chief technology guru for the Burning Man festival, and also founded a large online resource devoted to electronic music and related subcultures.

Revelation 13:18

666

The Number of the beast is described in the passage of Revelation 13:15–18. The actual number is only mentioned once, in verse 18. In the Greek manuscripts, the Book of Revelation is titled The Apocalypse of John where this number is rendered in Greek numerical form as χξϛ, or sometimes literally as ἑξακόσιοι ἑξήκοντα ἕξ, hexakósioi hexēkonta héx, "six hundred and sixty-six". There are several interpretations-translations for the meaning of the phrase "Here is Wisdom, Let him that hath understanding count the number of the beast" where the peculiar Greek word ψηφισάτω (psefisato) is used. Possible translations include not only "to count", "to reckon" but also "to vote" or "to decide".

Blockchain: the DNA of the Mark of the Beast, Artificial Intelligence

We seek to sound the alarm on developments regarding the Mark of the Beast ( Revelation 13:16-17). This video covers technology and the blockchain and how it all relates to the larger picture of the Mark of the Beast system.
This video also covers other subjects like controlled opposition. Lots of deception, propaganda, and lies out there.
The word( bible) is true. Just as prophetically what has been written is coming to pass, so is it true ( as it is written) that all who repent and trust in Yeshua/Jesus can be freed from the bondage of sin for the salvation of the soul and can gain a personal guide in these times!

Blockchain - A short introduction

Blockchain - A short introduction

Blockchain - A short introduction

What is the Blockchain? This 2 minute video explains it in a very easy way.
As usual, please leave you questions and ideas in the comments.
with love
your MinuteVideos TeamVideoScript:
Scene 1
Blockchain is a Peer to Peer software technology that protects the integrity of a digital piece of information. It was invented to create the alternative currency Bitcoin but may be used for other cryptocurrencies, online signature services, voting systems and many other applications. In this video we explain how it works and what makes it special.
Scene 2
Everyone uses paper money. When you get a 10 dollar bill you trust that it's not fake. If instead someone sent you an email saying "here's 10 dollars" you probably wouldn’t trust it. But when we "transfer money", use an ATM or pay with a deposit card that's pretty much exactly what we do. We're sending money in a digital message.
Scene 3
To make sure no one's cheating or sending money they don't have, these “messages” go through a few trusted banks that keep a record of everything. They know how much money everyone has and deduct it properly for every transaction.
Scene 4
But this becomes expensive when there’s a million transactions around the world every minute. The Economist estimates that banks charged us more than 1.7 trillion dollars to process these payments in 2014. That’s about 2% of the entire world economy! With blockchain we can save a lot of this cost because it lets us send money just like sending an email.
Scene 5
Instead of sending a lot of payment information through a few servers, blockchain uses thousands of personal computers on the internet. All transactions are copied and cross checked between every computer in a system wide accounting book called the ledger, which becomes very safe at scale.
Scene 6
Blockchain doesn’t just allow us to create safe money online, it lets us protect any piece of digital information. This could be online Identity cards, voter ballots, contracts and many other “legal instruments”, bringing bureaucracy into the 21st century.

Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, blockchain is still new and the communities are still exploring the best ways in which it can be used.

Can We Digitize the Voting System? Blockchain, Corruption, and Hacking | Brian Behlendorf

Can We Digitize the Voting System? Blockchain, Corruption, and Hacking | Brian Behlendorf

Can We Digitize the Voting System? Blockchain, Corruption, and Hacking | Brian Behlendorf

Anyone who's walked into a voting booth and scratched their preference onto a piece of paper knows the same thing: the voting process suffers from a dire lack of technology. Humanity put a man on the moon in 1969--why are we still voting on paper? Going digital isn't just a matter of convenience, but one of accountability—citizens the world over are increasingly losing trust in the democratic system, from miscounted votes, to denying eligible people the right to vote at all. So just how much can we digitize the act of voting? Perhaps blockchain—a public ledger technology where information is irreversibly recorded—can build a better system. Here, Internet pioneerBrian Behlendorf considers two aspects where blockchain can help, and one where it absolutely can't. Better tech can end voter discrimination at polling stations, and falsely reported totals at the state and national levels, but will we ever be able to vote on our mobile devices from the comfort of a blanket fort? Don't get your hopes up. Brian Behlendorf is the executive director of Hyperledger; for more info, visit http://www.hyperledger.org.

Transcript: Many people have asked: can blockchain technology help provide answers to challenges that typically have suffered from lack of technology, or that has suffered from poor technology applications. One of those being the way that voting works in the United States. I think of this in three distinct phases. There’s the phase before voting where keeping track of who is registered to vote and where they’re allowed to vote, it’s been harder than it should have been. We have a lot of examples of people showing up at polling places and being denied the right to vote and it seems like paperwork goes missing and people get removed from voting roles, that sort of thing. A public ledger that tracked who was registered to vote where and allowed people to look at that from their home machine and then confirm that when they showed up at the poll, would do a lot to reestablish trust in the process of registering to vote and validating that everybody who is entitled to vote is able to do that, providing an independent verification of that.
There’s a second phase I’ll get to in a bit, but there’s a third phase, which is after the vote, when you’re taking the totals that come from a polling place, that come from vote by mail for example in Oregon. We have to kind of trust that the system works. We have to hope that everything is counted correctly at the local level and then it’s totaled up correctly at the state level and then reported nationally et cetera. And we’re fortunately at a point where the basis of that trust hasn’t been violated yet, but in many countries it is. In many countries there’s not a lot of confidence that the total from a polling place is accurately summed up. So using a distributed ledger not to track the individual votes but to track the totals from each of the polling places would be a way to allow the public to understand: 'Okay the local polling place I went and voted at is reporting a thousand votes, 500 for candidate X, 500 for candidate Y, that seems about right. I don’t know if my vote specifically counted, but I know that at least the polling place I was at counted appropriately and they didn’t try to pretend they were 100,000 votes.' So at the beginning of that process and the tail end of that process using a public distributed ledger to record that makes a lot of sense.
But in the middle, the actual act of walking into a booth and registering a vote, or a lot of people want to do voting by mobile device or by computer; I’m very worried about the digitization of that. Our computers fail us all the time and malware and other threats could really step in and make it so that I think I’m voting for one candidate but it gets recorded for another. And we have to think, in the United States, we care quite a bit about the confidentiality of our vote even to the point where I get no receipt, I can’t go to a bar and prove that I voted for somebody and get a discount for it—that would be considered bribery. So we can’t simply come up with a system that puts all the original votes into a public ledger and provides proof that somebody voted a certain way or that becomes a corruptive process. So I think we still need voter-verified paper ballots as a path to auditing, but with the registration at the beginning and the summing at the end conducted by a public ledger I think we would do a tremendous amount to reestablish confidence in the voting system.

Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting Blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, Blockchain is still new and the communities are still exploring the best ways in which it can be used.

What is Blockchain

Developing Blockchain Software

This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges.
Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns.
C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

Understand the Blockchain in Two Minutes

Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet.
This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges.
Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns.
C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

The internet is evolving into a new technology paradigm based around smart systems, the blockchain, platforms, and IoT
in the coming years, these technologies will interact and converge in new and unpredictable ways
The convergence of IoT and blockchain will be a major part of this evolution, enabling new automated service systems and business models...
but many unresolved issues remain
IOTInternet of Things is the merging of our engineered physical environment with information systems to create smart adaptive objects and environments...
it is a fast-growing, increasingly complex network of connected physical systems that are able to process information and communicate peer to peer in order to enable common services.
These devices are becoming increasingly ubiquitous ranging from autonomous vehicles to sensors monitoring industrial processes, to smart homes and smart cities.
IoT is growing rapidly, according to Gartner the global IoT network will connect 26 billion devices by 2020.
The development of an IOT infrastructure to our economies will probably be the greatest engineering challenge of our time...
dealing with the sheer amount of data due to come on-stream and security are primary concerns...
before mainstream Internet-of-Things adoption can really take hold in a safe and sustainable fashion, these, among other issues, will need to be resolved.
Blockchain
The blockchain is a secure distributed database for recording transactions...
millions of computers networked to create a distributed database for recording and authenticating exchanges of value.
With the blockchain, value of any kind can be exchanged directly peer to peer without a centralized authority to record and validate the transaction.
The blockchain can provide an automated and secure transaction infrastructure for next generation IoT systems...
in its capacity to track billions of connected devices and enable the frictionless processing of transactions and coordination between devices.
This decentralized approach would eliminate single points of failure, bottlenecks and potentially make data and transactions more secure....
creating a more resilient ecosystem for devices to run on.
Likewise, it would automate transactions, enabling fully autonomous service systems; reduce cost and reduce settlement time from days to seconds
One example of an IoT Blockchain system is Slock, a door lock that is connected to a smart contract on the blockchain that controls when and who can open the lock.
“The owner of a Slock can set a deposit amount and a price for renting his property, and the user will pay that deposit through a transaction to the Ethereum blockchain, thereby getting permission to open and close that smart lock through their smart phone.” - Christoph Jentzsch
Such technology bridges the blockchain and the physical world by making automated smart contracts, thus enabling the frictionless and automated temporary exchange of assets such as bikes, parking lots or rooms.
"Smart contracts, a feature of “Bitcoin2.0” technologies such as Ethereum, could soon operate on the Internet of Things (IoT), control objects in the physical world, and power a new decentralized version of the sharing economy, for example sharing services similar to Uber and Airbnb that operate in pure P2P mode without centralized management." - Bitcoin MagazineLeveraging blockchain for IoT offers new ways to automate business processes and build distributed autonomous service systems...

Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet.
This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

I wanted to demonstrate that the concept of a blockchain that powers almost all of the modern cryptocurrencies is very simple at its core.
Bitcoin, Ethereum, Litecoin etc all are based on this blockchain technology. Many people think that the blockchain is a complicated thing while at it's core its just a clever use case of hashes.

We seek to sound the alarm on developments regarding the Mark of the Beast ( Revelation 13:16-17). This video covers technology and the blockchain and how it all relates to the larger picture of the Mark of the Beast system.
This video also covers other subjects like controlled opposition. Lots of deception, propaganda, and lies out there.
The word( bible) is true. Just as prophetically what has been written is coming to pass, so is it true ( as it is written) that all who repent and trust in Yeshua/Jesus can be freed from the bondage of sin for the salvation of the soul and can gain a personal guide in these times!

What is the Blockchain? This 2 minute video explains it in a very easy way.
As usual, please leave you questions and ideas in the comments.

your MinuteVideos TeamVideoScript:
Scene 1
Blockchain is a Peer to Peer software technology that protects the integrity of a digital piece of information. It was invented to create the alternative currency Bitcoin but may be used for other cryptocurrencies, online signature services, voting systems and many other applications. In this video we explain how it works and what makes it special.
Scene 2
Everyone uses paper money. When you get a 10 dollar bill you trust that it's not fake. If instead someone sent you an email saying "here's 10 dollars" you probably wouldn’t trust it. But when we "transfer money", use an ATM or pay with a deposit card that's pretty much exactly what we do. We're sending money in a digital message.
Scene 3
To make sure no one's cheating or sending money they don't have, these “messages” go through a few trusted banks that keep a record of everything. They know how much money everyone has and deduct it properly for every transaction.
Scene 4
But this becomes expensive when there’s a million transactions around the world every minute. The Economist estimates that banks charged us more than 1.7 trillion dollars to process these payments in 2014. That’s about 2% of the entire world economy! With blockchain we can save a lot of this cost because it lets us send money just like sending an email.
Scene 5
Instead of sending a lot of payment information through a few servers, blockchain uses thousands of personal computers on the internet. All transactions are copied and cross checked between every computer in a system wide accounting book called the ledger, which becomes very safe at scale.
Scene 6
Blockchain doesn’t just allow us to create safe money online, it lets us protect any piece of digital information. This could be online Identity cards, voter ballots, contracts and many other “legal instruments”, bringing bureaucracy into the 21st century.

Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, blockchain is still new and the communities are still exploring the best ways in which it can be used.

Can We Digitize the Voting System? Blockchain, Corruption, and Hacking | Brian Behlendorf

Anyone who's walked into a voting booth and scratched their preference onto a piece of paper knows the same thing: the voting process suffers from a dire lack of technology. Humanity put a man on the moon in 1969--why are we still voting on paper? Going digital isn't just a matter of convenience, but one of accountability—citizens the world over are increasingly losing trust in the democratic system, from miscounted votes, to denying eligible people the right to vote at all. So just how much can we digitize the act of voting? Perhaps blockchain—a public ledger technology where information is irreversibly recorded—can build a better system. Here, Internet pioneerBrian Behlendorf considers two aspects where blockchain can help, and one where it absolutely can't. Better tech can end voter discrimination at polling stations, and falsely reported totals at the state and national levels, but will we ever be able to vote on our mobile devices from the comfort of a blanket fort? Don't get your hopes up. Brian Behlendorf is the executive director of Hyperledger; for more info, visit http://www.hyperledger.org.

Transcript: Many people have asked: can blockchain technology help provide answers to challenges that typically have suffered from lack of technology, or that has suffered from poor technology applications. One of those being the way that voting works in the United States. I think of this in three distinct phases. There’s the phase before voting where keeping track of who is registered to vote and where they’re allowed to vote, it’s been harder than it should have been. We have a lot of examples of people showing up at polling places and being denied the right to vote and it seems like paperwork goes missing and people get removed from voting roles, that sort of thing. A public ledger that tracked who was registered to vote where and allowed people to look at that from their home machine and then confirm that when they showed up at the poll, would do a lot to reestablish trust in the process of registering to vote and validating that everybody who is entitled to vote is able to do that, providing an independent verification of that.
There’s a second phase I’ll get to in a bit, but there’s a third phase, which is after the vote, when you’re taking the totals that come from a polling place, that come from vote by mail for example in Oregon. We have to kind of trust that the system works. We have to hope that everything is counted correctly at the local level and then it’s totaled up correctly at the state level and then reported nationally et cetera. And we’re fortunately at a point where the basis of that trust hasn’t been violated yet, but in many countries it is. In many countries there’s not a lot of confidence that the total from a polling place is accurately summed up. So using a distributed ledger not to track the individual votes but to track the totals from each of the polling places would be a way to allow the public to understand: 'Okay the local polling place I went and voted at is reporting a thousand votes, 500 for candidate X, 500 for candidate Y, that seems about right. I don’t know if my vote specifically counted, but I know that at least the polling place I was at counted appropriately and they didn’t try to pretend they were 100,000 votes.' So at the beginning of that process and the tail end of that process using a public distributed ledger to record that makes a lot of sense.
But in the middle, the actual act of walking into a booth and registering a vote, or a lot of people want to do voting by mobile device or by computer; I’m very worried about the digitization of that. Our computers fail us all the time and malware and other threats could really step in and make it so that I think I’m voting for one candidate but it gets recorded for another. And we have to think, in the United States, we care quite a bit about the confidentiality of our vote even to the point where I get no receipt, I can’t go to a bar and prove that I voted for somebody and get a discount for it—that would be considered bribery. So we can’t simply come up with a system that puts all the original votes into a public ledger and provides proof that somebody voted a certain way or that becomes a corruptive process. So I think we still need voter-verified paper ballots as a path to auditing, but with the registration at the beginning and the summing at the end conducted by a public ledger I think we would do a tremendous amount to reestablish confidence in the voting system.

At IBM InterConnect 2016, Kathryn Guarini, Vice President, OfferingManagement for z Systems and LinuxONE, discusses the idea of cross-industry solutions, of which Blockchain is one. Blockchain is seen as the main technological innovation of Bitcoin, since it stands as proof of all the transactions on the network. A block is the 'current' part of a Blockchain which records some or all of the recent transactions, and once completed goes into the Blockchain as permanent database.
Ms. Guarini introduces Donna Dillenberger, IBM Fellow, who talks about Blockchain and its impact on various industries including financial technology . Ms. Dillenberger explains why you would want to run Blockchain on IBM z Systems. For more information about IBM z Systems and Blockchain visit IBM on the web at http://www.ibm.com/blockchain/z.html

The Bitcoin and Blockchain Technology Explained

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

-------------------------------------------------------------------
Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Developing Blockchain Software

This talk will explain what public blockchain systems like Bitcoin and Ripple are, the unique challenges of developing software for them, and how C++ helps to meet these challenges.
Security issues are paramount. Blockchain systems are open source, have large attack surfaces, and can cause significant financial damage if they have exploitable defects. Performance and scalability are also major concerns.
C++ provides a unique balance that helps meet these challenges. The language's design makes it possible to catch bugs at compile time, write modular code that can be tested, develop flexible data structures and manage resources. Yet, where performance is critical, it does not obscure what your code is making the computer actually do.

IoT Blockchain Convergence

Short video slide about the convergence of The Internet of Things(IoT) and the blockchain.

Transcription:
The internet is evolving into a new technology paradigm based around smart systems, the blockchain, platforms, and IoT
in the coming years, these technologies will interact and converge in new and unpredictable ways
The convergence of IoT and blockchain will be a major part of this evolution, enabling new automated service systems and business models...
but many unresolved issues remain
IOTInternet of Things is the merging of our engineered physical environment with information systems to create smart adaptive objects and environments...
it is a fast-growing, increasingly complex network of connected physical systems that are able to process information and communicate peer to peer in order to enable common services.
These devices are becoming increasingly ubiquitous ranging from autonomous vehicles to sensors monitoring industrial processes, to smart homes and smart cities.
IoT is growing rapidly, according to Gartner the global IoT network will connect 26 billion devices by 2020.
The development of an IOT infrastructure to our economies will probably be the greatest engineering challenge of our time...
dealing with the sheer amount of data due to come on-stream and security are primary concerns...
before mainstream Internet-of-Things adoption can really take hold in a safe and sustainable fashion, these, among other issues, will need to be resolved.
Blockchain
The blockchain is a secure distributed database for recording transactions...
millions of computers networked to create a distributed database for recording and authenticating exchanges of value.
With the blockchain, value of any kind can be exchanged directly peer to peer without a centralized authority to record and validate the transaction.
The blockchain can provide an automated and secure transaction infrastructure for next generation IoT systems...
in its capacity to track billions of connected devices and enable the frictionless processing of transactions and coordination between devices.
This decentralized approach would eliminate single points of failure, bottlenecks and potentially make data and transactions more secure....
creating a more resilient ecosystem for devices to run on.
Likewise, it would automate transactions, enabling fully autonomous service systems; reduce cost and reduce settlement time from days to seconds
One example of an IoT Blockchain system is Slock, a door lock that is connected to a smart contract on the blockchain that controls when and who can open the lock.
“The owner of a Slock can set a deposit amount and a price for renting his property, and the user will pay that deposit through a transaction to the Ethereum blockchain, thereby getting permission to open and close that smart lock through their smart phone.” - Christoph Jentzsch
Such technology bridges the blockchain and the physical world by making automated smart contracts, thus enabling the frictionless and automated temporary exchange of assets such as bikes, parking lots or rooms.
"Smart contracts, a feature of “Bitcoin2.0” technologies such as Ethereum, could soon operate on the Internet of Things (IoT), control objects in the physical world, and power a new decentralized version of the sharing economy, for example sharing services similar to Uber and Airbnb that operate in pure P2P mode without centralized management." - Bitcoin MagazineLeveraging blockchain for IoT offers new ways to automate business processes and build distributed autonomous service systems...
"The true value of the underlying technology -- the blockchain -- has only just begun to be explored, and potential applications to the Internet of Things and Smart Systems are vast."

Understand the Blockchain in Two Minutes

Over the past decade, an alternative digital paradigm has slowly been taking shape at the edges of the internet.
This new paradigm is the blockchain. After incubating through millions of Bitcoin transactions and a host of developer projects, it is now on the tips of tongues of CEOs and CTOs, startup entrepreneurs, and even governance activists. Though these stakeholders are beginning to understand the disruptive potential of blockchain technology and are experimenting with its most promising applications, few have asked a more fundamental question: What will a world driven by blockchains look like a decade from now?

Building a Blockchain in Under 15 Minutes - Programmer explains

I wanted to demonstrate that the concept of a blockchain that powers almost all of the modern cryptocurrencies is very simple at its core.
Bitcoin, Ethereum, Litecoin etc all are based on this blockchain technology. Many people think that the blockchain is a complicated thing while at it's core its just a clever use case of hashes.
Enjoy guys!

The Bitcoin Blockchain Explained

Forget the currency; it’s the protocol behind it that matters. Blockchains will mutate and take over everything we do on the Web.
Trusting strangers with your digital information may sound silly, but it’s actually a revolution in distributed computing. And one day, systems like Bitcoin could be the future of all secure digital transactions. Read more: http://bit.ly/29jiJ3B

Blockchain: the DNA of the Mark of the Beast, Artificial Intelligence

We seek to sound the alarm on developments regarding the Mark of the Beast ( Revelation 13:16-17). This video covers technology and the blockchain and how it all relates to the larger picture of the Mark of the Beast system.
This video also covers other subjects like controlled opposition. Lots of deception, propaganda, and lies out there.
The word( bible) is true. Just as prophetically what has been written is coming to pass, so is it true ( as it is written) that all who repent and trust in Yeshua/Jesus can be freed from the bondage of sin for the salvation of the soul and can gain a personal guide in these times!

your MinuteVideos TeamVideoScript:
Scene 1
Blockchain is a Peer to Peer software technology that protects the integrity of a digital piece of information. It was invented to create the alternative currency Bitcoin but may be used for other cryptocurrencies, online signature services, voting systems and many other applications. In this video we explain how it works and what makes it special.
Scene 2
Everyone uses paper money. When you get a 10 dollar bill you trust that it's not fake. If instead someone sent you an email saying "here's 10 dollars" you probably wouldn’t trust it. But when we "transfer money", use an ATM or pay with a deposit card that's pretty much exactly what we do. We're sending money in a digital message.
Scene 3
To make sure no one's cheating or sending money they don't have, these “messages” go through a few trusted banks that keep a record of everything. They know how much money everyone has and deduct it properly for every transaction.
Scene 4
But this becomes expensive when there’s a million transactions around the world every minute. The Economist estimates that banks charged us more than 1.7 trillion dollars to process these payments in 2014. That’s about 2% of the entire world economy! With blockchain we can save a lot of this cost because it lets us send money just like sending an email.
Scene 5
Instead of sending a lot of payment information through a few servers, blockchain uses thousands of personal computers on the internet. All transactions are copied and cross checked between every computer in a system wide accounting book called the ledger, which becomes very safe at scale.
Scene 6
Blockchain doesn’t just allow us to create safe money online, it lets us protect any piece of digital information. This could be online Identity cards, voter ballots, contracts and many other “legal instruments”, bringing bureaucracy into the 21st century.

Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, blockchain is still new and the communities are still exploring the best ways in which it can be used.
